emergency key 94. The auxiliary cylinder 92- carries a lug 95 which isadapted to be engaged by shoulders 96 on the cam to limit thell'lOVGlllGlltS of the cam under action o'l all keys except theemergency key. When mounted in the casing the cam 90 is adapted toengage the stumps or lugs ll) and (ll carried by the shutout lever andthe auxiliary controlling lever respectively, dependingupon the locationor these elements,

as will present-1y be described.

The operation is as follows:

Fig. 2 shows the positions ()l the elements when the door is open. Itwill be noted that in this position spring 39 has advanced or extendedthe auxiliary latch 2:38, and the head. or plate l0 reacting on theinclined edge all of the blocking slide 32 has raised this slidewithdrawing lug 36 from the path ol movement of the shoulder b7 on thelatch bolt 2-3. This latch bolt is thus -lree to retract or move intothe casing under the action of striking element .26 in coaction with thestriking plate 1? when the door is closed. It will also be noted thatthe master tumbler 46 is in its lowermost position with lug 49 carriedby the shutout lever 50 resting in the notch all. This tumbler.therefore, holds the shutout lever against movement and retains it inthe released position so that it cannot be moved to shutout position bythe thumb knob 56 while the door open.

Assuming; now that the door closed the elen'ients will be moved to thepositions shown in Fig. 3. In this position the projecting end o'l latchbolt .23 has entered the opening' 2% in the striking plate 17 and willretain the door in closed lJOSitlOIl. However. as the striking plate 17has no opening for the auxiliary latch i l this latch will be re tractedas shown. As this auxiliary latch n'ioved inwardly or retracted its head4-0 to acting; with the inclined edge 57 on tum bier 46 has raised thetumbler to the 1iiosition shown, and will retain it in this position aslong as the auriliary latch as is retracted. T he ii'iward movement (itthis latch. has also released the blocking slide 32 and it has beenmoved downwardly under the i :tion o'l spring 42 to bring lug 36 intoalignment with the shoulder 37. It will thus hold the latch bolt 23against retract-um by an external. means, such as a tool insertedbetween the door and the casing. The raising of the tun'ibler 4L6 hasalso released shutout lever 50 as the notch elf? is moved away from thelung l9. The shutout lever at) is, thereiliore, free to be swung to theshutout position by the thumb knob 56. if desired. It the room isunoccupied the elements will be lelt in the positions shown in Fig. 3.at which the lock is operable by all the keys, including the guest orpass keys. the master keys. and the emergency key. By reference to Fig.6 it will be seen that when under the action of any of the keys the cam90 is turned to the right or clockwise, as viewed in this figure, itwill engage the lug 61 on the auxiliary controlling lever 60 and bydepressing this lever through this lug will, by pressure (53 oi mastercontroliin clever til. cause its linger TO to engage head ill andretract the bolt from the striking plate and unlock the door.

r tssuinii'ig now that the room is occupied, the occupant turns thethumb knob 56 to the position shown in Fig. l swinging the shutout leveroil to bring lug all) into notch 48 in the tumbler l6. When the elementsare in these positions all oil the keys except the en'iergency key areblocked out or rendered inoperatire. Should now the occupant wish toopen the door all that is necessary to turn the usua knob To which willboth swing shoutout lever 50 to the released position and will. withdrawthe latch bolt 23 to allow the door to open. It thus releases theshutout mechanism and retracts the latch bolt, and the door may beopened without the necessity of manipulating the thumb knob 56, and bymanipulation of the main knob 76 only. This is accomplished follows:Turning the knob it rotates cam 73 swinging the free end o't hub lever71 rearwardly or to the right, as viewed in Fig. at. This will act onlinger of lever (Set. and swing linger ($2 to the .l- This fingeracting; on the end of lever 60 will depress this linger and cause thelug (ll reacting on the curved edge 97 of shutout lever 50 to swing thislever to the upright or released position shown in Fig. .5. At the sametime linger (52-3 operates intermediate lever '78 lifting; the blocking"plate 32 to release the latch bolt 23 and linger 70 engages the head.3.1v and retracts bolts 23. Thus turning cl the knob 76 releases theshutout n'ieclianisin and retracts the bolt 23) rendering the lock panicproof. .lt has been found that when the shutoutmechanism must bereleased by the thumb knob, in cases where there is a lire the occupanmay become so panic stricken to forget. to turn the thumb knob beforeoperating the main latch knob, and are thus trappetil in their rooms..lt will be apparent that such a condition can never happen with thislock.

liurthermore, when the sluitout 1nechanis n is set in the shutoutposition, that is, with the elements in the positions shown in Fig. lthe door can. be unlocked from the outside only by the emergency key allol the other keys being rendered inoperi-itive. It will be noted from aninspection of this ligure and Fig. 7 that the lugrGl on the lever (illhas been raised by the curved edge 97 on lever 50, out of the path ofmovement of the cam opcrateijl by the keys, the path of movement of thetree end of this cam being indicated by the dot and dash circle 98, and

as this cam can be swung by means of the on linger ill) llll

The loelt may, howev a, be operated bythe einergenqi hey flat. This her is oil? greater length than the othufkeys so as to control an additional pin tumbler 9; which controls thecylinder 92 carrying the stop hip 95. Thus by means of the emergency heythe 5am 90 may be given a complete revolution. the cylinder 9:2 underthese conditions turning: with the eylinder s7. Thus. although the lug;til is held by the shutout lever Till our of the path of movement of the"am, still the lug it) carried by the shutout lerer is with in the pathof movement of this ealn, as shown in Fin. T, and turning of the cam hrthe emergency key will. by aetion ot' the ram on lug t9, swing theshutout lever to the unlocked or released position shown in If 5s. lland 8. The cam Slll ma then be swung hart: about a quarter turn past thelog: (it. which will be lifted to alltm' the rain to pass and by thenturning" the 'am rloelcwise or to the right, as viewd in Fin. 8. it willmeagre the lug (ll and ret'aet the lateh bolt 23 allowing the door to beopened as desrrihed above.

To do this the emergencylief may he used in the reverse operation from that just desrribed. thatis by turning it in the oppo.:ite direction or umtereloekwise, as 'iewedin Figs. 6 and til. it will ei'igzu i'e the left hand side ol lue' ll)and swing it. from alignment with notch 4;? to notch' lfil or into theshutout position.
